For the PC infected by a virus or malware

The PC must have the same Windows operating system (OS) architecture (32-bit or 64-bit) as Windows Defender Offline. Bootable media created on any version of Windows can be run on any other version of Windows. The only thing that needs to match is the architecture of Windows Defender Offline and the OS of the infected machine.

BitLocker must be disabled to use Windows Defender Offline.

For the PC on which you create the bootable media

Administrator account: A user account with administrator privileges to create the bootable media.

Internet connection: An Internet connection to install and download the latest virus and spyware definitions for Windows Defender Offline.
